Routing Node Caches Location Data to Reduce HLR Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing use of social networking and blogging services through mobile devices is putting a burden on existing mobile network equipment, particularly due to the need for multiple nodes to process and deliver messages, and the frequent querying of Home Location Registers (HLR) to route SMS messages.
Innovation Solution
Implementing a system with a routing node that intercepts mobility management messages to cache location information, allowing for the storage and retrieval of this information without querying the HLR, and using a rules database to manage message delivery based on subscriber-specific rules, thereby reducing the load on HLR queries and enhancing message delivery efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If HLR is queried to retrieve mobile device location for routing SMS messages, then message delivery is enabled, but network equipment burden increases
Solution Approach 1:
The system performs preliminary action by intercepting and caching mobility management messages containing location information before they are needed for message routing. The routing node proactively stores location data in a database when mobility management messages are received, so that when SMS messages need to be routed, the location information is already available without requiring HLR queries, thus reducing network equipment burden while maintaining delivery efficiency
2Reliability
If multiple nodes are used to process and deliver social networking messages, then message processing is enabled, but network complexity increases
Solution Approach 1:
The system merges the functions of multiple nodes by enabling a single routing node to perform both message type conversion and message delivery. The routing node integrates the capabilities of what were previously separate entities (SMPP gateway for format conversion and SMSC for delivery), consolidating these functions into one node that can convert social networking messages to SMS format and deliver them using cached location information, thereby reducing network complexity while maintaining processing reliability

AI summary
Methods, systems, and computer readable media for controlling the delivery of a social networking service originated message directed to a mobile device are disclosed. According to one example, the method performed at a routing node includes intercepting a mobility management message that includes location information associated with a mobile device, storing the location information associated with the mobile device in a location database, and receiving a social networking service originated message directed to the mobile device, wherein the message includes media content. The method further includes extracting the location information associated with the mobile device from the location database and delivering the media content to the mobile device using the extracted location information from the location database.
